Highlights: Higher vitamin D levels in midlife were linked to lower levels of tau protein, a key marker associated with Alzheimer’s disease, years later The findings show a connection, but they do not prove that vitamin D directly reduces dementia risk Researchers found no link between vitamin D levels and another Alzheimer’s marker, amyloid beta […]

A 30-Year-Old Flu Shot Still Works Today With One Big Problem
A 30-year-old flu vaccine still fights some modern viruses—but leaves a critical weakness exposed. Researchers have uncovered new insights into how long flu vaccine protection can last by revisiting blood samples from people vaccinated in 1994. By examining these preserved samples, scientists found that the immune response triggered by that vaccine could still recognize and […]

Widely Available Drug Found To Ease One of Long COVID’s Most Stubborn Symptoms
An established drug shows unexpected promise against long COVID fatigue. A widely used antidepressant may offer unexpected relief for one of long COVID’s most stubborn symptoms. In a new clinical trial, researchers found that fluvoxamine can significantly reduce persistent fatigue, a condition that continues to disrupt daily life for millions worldwide. The study, led in […]
Stopping Weight-Loss Drugs Like Ozempic Can Quickly Erase Heart Benefits
The benefits of GLP-1 drugs may fade faster than expected when treatment is interrupted. GLP-1 drugs have quickly moved from niche diabetes treatments to some of the most talked-about medications in the country. Drugs such as semaglutide and tirzepatide are now used by about one in eight U.S. adults, not only for blood sugar control […]
A 500-Million-Year-Old Surprise Is Forcing Scientists to Rethink Spider Evolution
A tiny claw in a 500-million-year-old fossil just rewrote the origin story of spiders. After a full day of teaching, Rudy Lerosey-Aubril turned to a task he found especially rewarding: preparing a Cambrian arthropod fossil for study. As he carefully cleaned the specimen, it initially appeared typical for its age. But one detail quickly stood […]
Ancient Carbon Is Flooding Arctic Rivers As Permafrost Melts Faster
Thawing Arctic ground is unleashing ancient carbon—and speeding up climate change. Scientists have taken a detailed new look at what happens when Arctic permafrost begins to thaw, revealing major changes to water flow and carbon movement across northern Alaska. The research, led by geoscientist Michael Rawlins at the University of Massachusetts Amherst, provides one of […]
